I have Kurz's and Pavel's publications which are excellent but recently bought a new book by David De Angelis - Power-Flex stretching after it was recommended on the dragondoor forum (pavel). Itís not widely known because it has only been translated into English fairly recently. I would certainly recommend it for those wanting to improve their functional flexibility martial arts.

I'm always a bit dubious about new books on stretching, but this guy really knows his stuff and backs it up with scientific knowledge and application (he is a gymnast and a martial artist).
